Title: Predicting device and analyzing device for semiconductor element characteristics
Inventor: SAITO SHINICHI
IPC: H01L29/78
Filed: 2001-06-14
Abstract: PROBLEM TO BE SOLVED: To extract an element parameter from a measured value by simply and quantitively evaluating the CV characteristics in an accumulated state. SOLUTION: The potential form in an accumulated state is approximated with an index function, and the solution of a Schroedinger equation is strictly and analytically acquired with no contradiction with a quantum statistic. Thus, the CV characteristics are quantitatively calculated. By comparing the calculation result with a measured value, element parameters such as the electrical thickness of a gate insulating film, substrate concentration, and flat band voltage are extracted. With the use of an electric characteristics evaluating device, the calculation which requires one or two days for completion by a conventional numerical solving method is done within a few minutes. The thickness of the gate insulating film in electrical meaning is acquired with the precision of 0.05 nm or less the measured value of CV characteristics.
